Systems and methods for informing and evaluating neuromodulation therapy are disclosed herein. A system configured in accordance with embodiments of the present technology can include, for example, a guidewire having a proximal portion, a distal portion configured to be positioned at a target site in a blood vessel of a human patient, and a sensing element positioned along the distal portion. The sensing element can be a pressure sensing element, a flow sensing element, an impedance sensing element, and/or a temperature sensing element. The system can further include a controller configured to obtain one or more measurements related to a physiological parameter of the patient via the sensing element. Based on the measurements, the controller can determine the physiological parameter and compare the parameter to a predetermined threshold. Based on the comparison, the controller and/or the operator can assess the likelihood of the patient benefiting from neuromodulation therapy.

The present disclosure provides devices, systems and methods for hyperthermia cancer treatment by supplying ferromagnetic nanoparticles to a target area having or suspected of having cancer cells, the ferromagnetic nanoparticles are configured to attach to the cancer cells and heat by absorbing magnetic energy, and radiating the target area with microwaves such that the target area is within a nearfield range of the radiated microwave, and the microwave radiation nearfield is magnetically biased such that the ratio of magnetic energy to electric energy is greater than 1.

The invention relates to medical therapy of detrimental lesions. A system treats with non-invasive arrays of non-ionizing energy-radiation sources. The external sources focus energy dose distribution to a selected volume in a body. Energy output is directed towards a pathologic location and quenched around other sites or healthy tissue. Beam aiming is done without source movement. Targeted, volumetrically discrete energy deposition can beneficially manipulate lesions within the body. The purpose of the focused and enhanced energy deposition is to repair or disable pathologic physiology or structures, nerve pathways, extracellular fluid, and misfolded proteins. Locally augmented energy is used to enhance immunity, release pharmaceutical compounds from energy-sensitive vesicles and reconfigure or eliminate misfolded proteins and their aggregates. Targeted tissue may have enhanced sensitivity to received energy via a non-ionizing-radiation, treatment-localizing agent. This system optimizes delivery of non-ionizing, non-ablating electromagnetic or mechanical energy, degrading or repairing an abnormality upon interaction with it.

Methods, systems, and devices for wireless signal transmission are described. A fractal antenna may be utilized to wirelessly communicate with a transmitter implanted within or located external to the patient. The fractal antenna may be implanted within the patient and may be coupled with a lead also implanted within the patient. The characteristics of the fractal antenna may allow for enhanced data transmission between the antenna and the transmitter while reducing the need for implanted wires to connect the transmitter and leads.

Provided are a heat treatment device and a method and apparatus for detecting an abnormality in the heat treatment. The heat treatment device includes a radio wave signal generator configured to generate target radio wave signals for heat treatment, a radio wave signal transmitter which includes an antenna configured to transmit the target radio wave signals to a body, a radio wave signal detector configured to detect the target radio wave signals from the antenna, a ratio information determiner configured to determine ratio information about a signal phase and a signal strength by comparing a reference target radio wave signal included in the detected target radio wave signals and each of the other target radio wave signals, and an abnormality occurrence determiner configured to determine whether an abnormality occurs in the heat treatment device based on the determined ratio information and predefined reference ratio information.

A method for treating a patient that includes directing first microwave energy towards excitable tissue in a patient and second microwave energy towards the excitable tissue at an angle from the first microwave energy. The first electric field from the first microwave energy overlaps with the second electric field from the second microwave energy at the excitable tissue so as to alter a physiological function of the excitable tissue. Third microwave energy can optionally be directed towards the excitable tissue for overlapping with the first microwave energy and the second microwave energy at the excitable tissue.
